What is an ethane compressor?

A specialized piece of machinery, an ethane compressor, compresses ethane gas to greater pressures for various industrial uses.  Natural gas frequently contains the hydrocarbon gas ethane, widely used in petrochemical, energy, and gas processing sectors. An ethane compressor’s main objective is to raise ethane gas’s pressure to make transportation, storage, and use easier. To satisfy the needs of downstream operations, including ethane recovery, ethylene generation, and other petrochemical processes, ethane compression is required.

What is the purpose of the ethane compressor?

What is the ethane compressor used for? Ethane gas is compressed with the use of an ethane compressor. Ethane is a hydrocarbon molecule frequently present in petroleum and natural gas. When the temperature and pressure are normal, it is a colourless and odourless gas. An ethane compressor’s main function is to raise ethane gas pressure so that it can be transported over long distances or processed for use in various industrial applications. It is to reduce pipeline friction and keep an effective flow rate, and ethane gas must be compressed. The size of the gas is reduced while its pressure is raised during the compression process. Pipelines are commonly used to deliver compressed ethane to petrochemical facilities and used as feedstock for various operations. To make ethylene, a crucial component of plastics, resins, and other chemical products, ethane is frequently employed as a raw material. Ethane can be transported and used in subsequent industrial operations more affordably by compressing it.

In response to the function of ethane compressors in the oil and gas industry:

In the oil and gas industry, ethane compressors are especially important for transporting and processing natural gas. An essential feedstock for many industries, including petrochemicals and plastics, ethane is a hydrocarbon gas frequently found in natural gas reservoirs. Following is a breakdown of the function and importance of ethane compressors in the oil and gas industry:

Extraction and processing: 

When crude oil and natural gas are produced, ethane is frequently extracted together with other natural gas constituents. Ethane is detached from the natural gas stream using ethane compressors through gas processing or gas conditioning. These compressors aid in raising the pressure and density of the gas mixture, which enables effective ethane separation from the other constituents.

Ethane recovery: 

After being separated, ethane is frequently extracted and purified as a feedstock in many industrial processes. The extracted ethane is compressed using ethane compressors to greater pressure for pipeline transit or further processing.

Pipeline Transportation:

 Ethane is frequently transported through pipelines from the extraction site to processing facilities or distribution centers, along with other natural gas liquids (NGLs). Ethane compressors are deployed along the pipeline network to maintain the necessary pressure levels and guarantee the ethane flows smoothly. The effective and uninterrupted passage of ethane is ensured by these compressors, which aid in overcoming frictional losses and pressure dips during transit.

Storage and Refrigeration:

 Before being employed as a feedstock or transferred to end consumers, ethane is frequently kept in chilled storage tanks or underground storage facilities. Ethane compressors are essential for preserving the pressure and temperature ranges required for safe storage and refrigeration. The compressor works to keep ethane gas liquid by compressing it, which makes for efficient storage and lowers the possibility of leaks or mishaps.

Petrochemical Industry: 

Ethane is an essential raw element in ethylene synthesis, which is a necessary component in creating many petrochemical goods, such as plastics, synthetic fibers, and solvents. Ethane compressors deliver ethane to petrochemical facilities, which is used in the steam-cracking process to create ethylene. These compressors are essential for the ethane supply to remain steady and stable in order to satisfy the petrochemical industry’s demand.

The Most Important Factors Affecting Ethane Compression Effectiveness:

Inlet Pressure: 

Ethane entering the compressor at high or low pressure has a big impact on how efficient it is. Efficiency is increased because it takes less effort to compress the ethane to the necessary discharge pressure at higher intake pressures. Based on the compressor system’s unique needs and constraints, optimising the inlet pressure is crucial.

Discharge Pressure:

 The intended ethane discharge pressure influences the compressor’s effectiveness. Higher discharge pressures generally need greater energy input, which lowers efficiency. To achieve maximum efficiency, choosing a discharge pressure suitable for the process while consuming the least amount of energy is essential.

Compression Ratio: 

The ratio between the input and discharge pressures is the compression ratio. It is crucial to decide how effectively the ethane compressor works. Because more energy is required, higher compression ratios typically have lesser efficiency. To balance efficiency and performance, choosing the compression ratio correctly based on the particular application is important.

Flow Rate: 

Ethane via the compressor must flow at a certain rate, which impacts its effectiveness. Higher flow rates would necessitate bigger compressor units or more parallel-operating compressors, which could reduce efficiency. Designing the compressor system to effectively manage the desired flow rate while preventing needless energy losses is crucial.


 The temperature of the ethane during compression has an impact on the efficiency of ethane compression. Due to greater energy losses and decreased volumetric efficiency, higher temperatures might result in decreased efficiency. Appropriate cooling and temperature management mechanisms should be implemented to ensure ideal operating conditions and boost effectiveness.

Compressor Design and Equipment Selection: 

 Efficiency is heavily influenced by the design and equipment selection of the compressor, including the kind of compressor (reciprocating, screw, diaphragm, etc.), the number of stages, and particular components. The best design and equipment must be chosen to obtain high efficiency in ethane compression because every type of compressor has benefits and limits in terms of efficiency.


What is the ethane compressor used for? It is used in petrochemical industries. Compressing natural gas liquids like ethane makes ethane compressors a crucial component in natural gas processing. Typically, downstream natural gas processing facilities remove and treat NGLs from raw natural gas streams. We provide various nations in Asia, America, Africa, Europe, Australia, etc., with compressors. HUAYAN are working hard to establish itself as an industry leader because we have a thorough grasp of the demands and specifications of the compressor industry.
